Description

Technical Field

[0001] This application relates to the field of shadowless lamp technology, and more particularly to a shadowless lamp and operating room system. Background Technology

[0002] Medical shadowless lamps, also known as surgical shadowless lamps, are a type of lighting equipment specifically designed for use in medical operating rooms. They are designed to provide doctors with a bright and shadow-free lighting environment during surgery, ensuring that surgeons can clearly see the various fine structures inside the patient's body cavity and at the incision site.

[0003] The patent with publication number CN222703221U designed a medical shadowless lamp that can be installed on the ground or suspended to adapt to various surgical scenarios. However, when changing the medical shadowless lamp from ground installation to suspension installation, the base, hollow rectangular column and extension column need to be removed, and then the connector is connected to the ceiling, which makes the installation relatively complicated. Utility Model Content

[0004] This application discloses a shadowless lamp and operating room system, which can improve the ease of installation of the shadowless lamp.

[0005] To achieve the above objectives, in a first aspect, embodiments of this application disclose a shadowless lamp, comprising:

[0006] Base;

[0007] A walking wheel assembly, the walking wheel assembly being connected to the base and located on a first side of the base, the walking wheel assembly being used to move the base relative to the ground;

[0008] A bracket, which is connected to the base and located on a second side of the base, wherein the first side and the second side are arranged opposite each other in a vertical direction;

[0009] The lamp body is connected to the bracket and has a first state and a second state. When the lamp body is in the first state, the light-emitting surface of the lamp body faces the side where the base is located; when the lamp body is in the second state, the light-emitting surface of the lamp body faces away from the side where the base is located.

[0010] The walking wheel assembly has an installation space on the side near the bracket. The installation space is used to install a guide rail so that the walking wheel assembly can be suspended on the guide rail when the base is inverted.

[0011] In one alternative embodiment, the lamp body is rotatably connected to the bracket to switch the lamp body between the first state and the second state.

[0012] In one optional embodiment, the walking wheel assembly includes a first walking wheel and a second walking wheel spaced apart. A first subspace is formed on the side of the first walking wheel near the bracket, and a second subspace is formed on the side of the second walking wheel near the bracket. The installation space includes the first subspace and the second subspace.

[0013] The first subspace and the second subspace are respectively used to install different parts of the guide rail, so that when the base is inverted, the first traveling wheel and the second traveling wheel can be suspended on the guide rail.

[0014] In one alternative embodiment, the wheel assembly further includes a third wheel and a fourth wheel, with the first wheel and the second wheel both located between the third wheel and the fourth wheel.

[0015] In one alternative embodiment, the first wheel is movably connected to the base so that the first wheel moves toward the side away from the first subspace.

[0016] In one alternative embodiment, the first wheel is rotatably connected to the base so that the first wheel rotates toward the side away from the first subspace.

[0017] In one optional embodiment, a rotating shaft is fixedly connected to the base, the first traveling wheel passes through the rotating shaft and is rotatably connected to the rotating shaft, a locking nut is sleeved on the rotating shaft, the locking nut is located on one side of the first traveling wheel and is threadedly connected to the rotating shaft, and the locking nut can stop the first traveling wheel against the base.

[0018] In one alternative embodiment, the bracket includes a first telescopic rod connected to the base, the lamp body being connected to the first telescopic rod, and the first telescopic rod being capable of driving the lamp body to move up and down in the vertical direction.

[0019] In one optional embodiment, the bracket further includes a second telescopic rod, the lamp body being connected to the first telescopic rod via the second telescopic rod, the telescopic direction of the second telescopic rod being parallel to the horizontal direction.

[0020] Secondly, this application provides an operating room system, comprising:

[0021] guide:

[0022] The shadowless lamp described in any of the above embodiments;

[0023] The shadowless lamp has a first working state and a second working state. When the shadowless lamp is in the first working state, the base is upright, the lamp body is in the first state, and the walking wheel assembly can contact the ground. When the shadowless lamp is in the second working state, the base is inverted, the lamp body is in the second state, the guide rail passes through the installation space, and the walking wheel assembly is suspended on the guide rail and can roll relative to the guide rail.

[0024] Compared with related technologies, the beneficial effects of this application are:

[0025] In this embodiment, the shadowless lamp includes a base, a wheel assembly, a bracket, and a lamp body. The lamp body is mounted on the base via the bracket, and the wheel assembly is located on the base. In operating room scenarios requiring close-range, small-area lighting, the wheel assembly can be placed on the ground. In this case, the lamp body is at a lower height, enabling close-range, small-area lighting. Furthermore, by driving the wheel assembly to move relative to the ground, the position of the lamp body within the operating room can be changed to adjust the lighting area. When a wider lighting range is required in the operating room, the base can be inverted, and the wheel assembly can be suspended from a guide rail on the ceiling of the operating room. In this case, the lamp body is at a higher height, enabling wide-area lighting. Furthermore, by controlling the wheel assembly to roll relative to the guide rail, the position of the lamp body within the operating room can be changed to adjust the lighting area.

[0026] As can be seen, this application can quickly switch the shadowless lamp between two installation states simply by inverting the base and suspending the walking wheel assembly on the guide rail. During this process, there is no need to disassemble the base, nor is it necessary to use screws or other fasteners to fix the base to the ceiling of the operating room, which greatly improves the ease of installation of the shadowless lamp.

[0043] The shadowless lamp and operating room system provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0044] like Figures 1 to 4 As shown in the figure, this application discloses a shadowless lamp, including:

[0045] The system comprises a base 100, a wheel assembly 200, a bracket 300, and a lamp body 400. The wheel assembly 200 is connected to the base 100 and located on the first side of the base 100. The wheel assembly 200 is used to move the base 100 relative to the ground. Specifically, taking the base 100 in an upright position as an example, the first side of the base 100 is the lower side of the base 100, and the second side of the base 100 is the upper side of the base 100; taking the base 100 in an inverted position as an example, the first side of the base 100 is the upper side of the base 100, and the second side of the base 100 is the lower side of the base 100.

[0046] The bracket 300 is connected to the base 100 and located on the second side of the base 100. The first side and the second side are vertically opposite each other. The lamp body 400 is connected to the bracket 300 and has a first state and a second state. When the lamp body 400 is in the first state, the light-emitting surface of the lamp body 400 faces the side where the base 100 is located; when the lamp body 400 is in the second state, the light-emitting surface of the lamp body 400 faces away from the side where the base 100 is located. It should be noted that when the walking wheel assembly 200 is installed on the ground, the lamp body 400 can be in the first state, such as... Figure 1As shown; when the traveling wheel assembly 200 is suspended from the guide rail 700, the lamp body 400 can be in the second state, such as... Figure 3 As shown.

[0047] The wheel assembly 200 has an installation space 500 on the side near the bracket 300. The installation space 500 is used to install the guide rail 700 so that the wheel assembly 200 can be suspended on the guide rail 700 after the base 100 is inverted.

[0048] In this embodiment, the shadowless lamp includes a base 100, a wheel assembly 200, a bracket 300, and a lamp body 400. The lamp body 400 is mounted on the base 100 via the bracket 300, and the wheel assembly 200 is disposed on the base 100. In operating room scenarios requiring close-range, small-area lighting, the wheel assembly 200 can be placed on the ground. In this case, the lamp body 400 is at a lower height, enabling close-range, small-area lighting. Furthermore, by driving the wheel assembly 200 to move relative to the ground, the position of the lamp body 400 within the operating room can be changed to adjust the lighting area. When a wider lighting range is required in the operating room, the base 100 can be inverted, and the wheel assembly 200 can be suspended from the guide rail 700 on the ceiling of the operating room. In this case, the lamp body 400 is at a higher height, enabling wide-area lighting. Furthermore, by controlling the wheel assembly 200 to roll relative to the guide rail 700, the position of the lamp body 400 within the operating room can be changed to adjust the lighting area.

[0049] As can be seen, this application can quickly switch the shadowless lamp between two installation states simply by inverting the base 100 and suspending the walking wheel assembly 200 on the guide rail 700. In this process, there is no need to disassemble the base 100, nor is it necessary to use screws or other fasteners to fix the base 100 to the top of the operating room, which greatly improves the ease of installation of the shadowless lamp.

[0050] In one alternative embodiment, please refer to Figure 1 and Figure 3 The lamp body 400 is rotatably connected to the bracket 300, allowing the lamp body 400 to switch between a first state and a second state. For example, the axis of rotation between the lamp body 400 and the bracket 300 can be parallel to the horizontal direction.

[0051] In this embodiment, the lamp body 400 is rotatably connected to the bracket 300, which not only makes it easy to switch the lamp body 400 between the first and second states, but also allows for precise adjustment of the lighting direction and angle of the lamp body 400 according to the specific needs of the surgery, ensuring that the surgical area obtains ideal lighting effects, providing doctors with a clearer surgical field of vision, improving the accuracy and safety of surgical operations, and further enhancing the practicality and adaptability of the shadowless lamp.

[0052] In some embodiments, the lamp body 400 and the bracket 300 can be detachably connected. By changing the installation position between the lamp body 400 and the bracket 300, the lamp body 400 can switch between a first state and a second state. Alternatively, in other embodiments, the lamp body 400 has two light-emitting units inside, with the light-emitting surfaces of the two units facing opposite directions, one towards the side where the base 100 is located and the other away from the side where the base 100 is located. By controlling whether the two light-emitting units emit light, the lamp body 400 can switch between a first state and a second state.

[0053] In one alternative embodiment, please refer to Figure 2 and Figure 4 The walking wheel assembly 200 includes a first walking wheel 210 and a second walking wheel 220 spaced apart. A first subspace 510 is formed on the side of the first walking wheel 210 near the bracket 300, and a second subspace 520 is formed on the side of the second walking wheel 220 near the bracket 300. The mounting space 500 includes the first subspace 510 and the second subspace 520. The first subspace 510 and the second subspace 520 are respectively used to mount different parts of the guide rail 700 so that the first walking wheel 210 and the second walking wheel 220 can be suspended on the guide rail 700 after the base 100 is inverted.

[0054] In actual installation, the corresponding parts of the guide rail 700 are respectively installed into the first subspace 510 and the second subspace 520. When the base 100 is inverted, the first traveling wheel 210 and the second traveling wheel 220 can be stably suspended on the guide rail 700 and can roll along the guide rail 700. It can be seen that this embodiment achieves multi-point suspension of the shadowless lamp through the cooperation of multiple traveling wheels and their corresponding subspaces with the guide rail 700. Compared with a single suspension point, multi-point suspension can more evenly distribute the weight of the shadowless lamp, reduce the risk of structural deformation or damage caused by excessive local stress, and provide continuous and stable lighting for surgery.

[0055] In one alternative embodiment, please refer to Figure 2 The wheel assembly 200 also includes a third wheel 230 and a fourth wheel 240, with the first wheel 210 and the second wheel 220 both located between the third wheel 230 and the fourth wheel 240.

[0056] In this embodiment, when the shadowless lamp is in a ground-moving state, multiple wheels make contact with the ground together, providing more uniform support and enhancing the stability of the shadowless lamp when moving on the ground, reducing shaking or bumping caused by uneven ground or uneven force on a single wheel; furthermore, the first wheel 210 and the second wheel 220 are both located between the third wheel 230 and the fourth wheel 240, so the distance between the first wheel 210 and the second wheel 220 is relatively small, which can reduce the size of the guide rail 700, thereby allowing for more flexible arrangement of the guide rail 700 to better adapt to the spatial layout and needs of the operating room.

[0057] In one alternative embodiment, please refer to Figures 5 to 7 The first wheel 210 is movably connected to the base 100 so that the first wheel 210 moves toward the side away from the first subspace 510. Exemplarily, the first wheel 210 and the base 100 can be slidably connected or rotatably connected, and this application does not limit this.

[0058] In this embodiment, please refer to Figure 8 When suspending the traveling wheel assembly 200 onto the guide rail 700, the first traveling wheel 210 can be controlled to move away from the first subspace 510, thereby increasing the gap between the first traveling wheel 210 and the second traveling wheel 220. Then, the guide rail 700 can be inserted into the installation space 500. This facilitates the insertion of the guide rail 700 into the installation space 500 and reduces the difficulty of inserting the traveling wheel assembly 200 into the guide rail 700. Furthermore, the size of the guide rail 700 may vary depending on different installation requirements. The movable design of the first traveling wheel 210 allows the shadowless lamp to adapt to guide rails 700 of different sizes. For example, when the size of the guide rail 700 is slightly larger, the first traveling wheel 210 can be controlled to move outward, thereby expanding the installation space 500 and allowing the guide rail 700 to be smoothly inserted into the installation space 500.

[0059] In one alternative embodiment, please refer to Figures 5 to 7 The first traveling wheel 210 is rotatably connected to the base 100 so that the first traveling wheel 210 rotates toward the side away from the first subspace 510.

[0060] In this embodiment, the first traveling wheel 210 is rotatably connected to the base 100. The rotatable connection structure is simple and reliable, easy to manufacture and install, and can ensure the stability and flexibility of the first traveling wheel 210 during the activity process.

[0061] In other embodiments, the second wheel 220 may also be rotatably connected to the base 100 so that the second wheel 220 rotates toward the side away from the second subspace 520.

[0062] In one alternative embodiment, please refer to Figure 5A rotating shaft 610 is fixedly connected to the base 100. A first traveling wheel 210 passes through the rotating shaft 610 and is rotatably connected to the rotating shaft 610. A locking nut 620 is sleeved on the rotating shaft 610. The locking nut 620 is located on one side of the first traveling wheel 210 and is threadedly connected to the rotating shaft 610. The locking nut 620 can stop the first traveling wheel 210 against the base 100. For example, the base 100 is provided with a rotating frame 110, and the rotating shaft 610 is fixed to the rotating frame 110. For example, the rotating shaft 610 can be the shank of a screw. In this case, the rotating frame 110 is provided with a through hole, the screw passes through the through hole, and the screw is fixed to the rotating frame 110 by a fixing nut 630.

[0063] In actual operation, when it is necessary to fix the position of the first traveling wheel 210, the locking nut 620 is tightened to make the first traveling wheel 210 abut against the base 100, thereby restricting the rotation of the first traveling wheel 210; when it is necessary to adjust the position of the first traveling wheel 210, the locking nut 620 is loosened, allowing the first traveling wheel 210 to rotate freely. In this embodiment, the locking nut 620 can flexibly fix or release the first traveling wheel 210, ensuring that the equipment will not be affected by unexpected movement of the traveling wheel when a stable state is required.

[0064] In one alternative embodiment, please refer to Figure 1 The bracket 300 includes a first telescopic rod 310, which is connected to the base 100. The lamp body 400 is connected to the first telescopic rod 310, and the first telescopic rod 310 can drive the lamp body 400 to move up and down in the vertical direction. For example, the first telescopic rod 310 can be implemented using various mechanical structures, such as a threaded telescopic rod or a sleeve telescopic rod, in conjunction with a suitable drive mechanism (such as motor drive, manual adjustment, etc.).

[0065] This embodiment achieves vertical height adjustability of the lamp body 400 through the first telescopic rod 310. In different surgical scenarios, the height of the lamp body 400 can be flexibly adjusted according to the height of the operating table, the location of the surgical site, and the doctor's operating habits to ensure optimal lighting in the surgical area.

[0066] In one alternative embodiment, please refer to Figure 1 The bracket 300 also includes a second telescopic rod 320. The lamp body 400 is connected to the first telescopic rod 310 through the second telescopic rod 320. The telescopic direction of the second telescopic rod 320 is parallel to the horizontal direction.

[0067] This embodiment utilizes a second telescopic rod 320 to allow the lamp body 400 to move horizontally, thereby expanding the illumination range and adjustment flexibility of the shadowless lamp. During surgery, the surgeon can easily move the lamp body 400 to the optimal illumination position according to actual needs, enabling it to better adapt to various surgical scenarios and different surgical operation requirements, providing comprehensive lighting support for the surgery.

[0068] This application also discloses an operating room system, including a guide rail 700 and the shadowless lamp described in any of the above embodiments. Exemplarily, the cross-section of the guide rail 700 may be I-shaped.

[0069] The shadowless lamp has a first working state and a second working state. In the first working state, the base 100 is upright, the lamp body 400 is in the first state, and the wheel assembly 200 can contact the ground. In the second working state, the base 100 is inverted, the lamp body 400 is in the second state, the guide rail 700 passes through the installation space 500, and the wheel assembly 200 is suspended from the guide rail 700 and can roll relative to the guide rail 700. It should be noted that when the base 100 is upright, the wheel assembly 200 faces downwards; when the base 100 is inverted, the wheel assembly 200 faces upwards.

[0070] The operating room system of this application organically combines two working modes: floor-mounted and suspended installation, forming a complete and flexible lighting solution. In the actual operating room environment, the working mode of the shadowless lamp can be flexibly selected according to factors such as the type and scale of the surgery and the spatial layout of the operating room. For some minor surgeries or situations requiring frequent movement of lighting equipment, the floor-mounted mode can be used; while for major surgeries or surgeries requiring fixed lighting positions and high light stability, the suspended installation mode can be switched to. Through the cooperation of the guide rail 700 and the traveling wheel assembly 200, not only is rapid installation and conversion achieved, but the shadowless lamp can also be easily moved along the guide rail 700 in the suspended state, further improving the flexibility and adaptability of the equipment, effectively meeting the diverse and complex lighting needs of modern operating rooms, and improving the overall work efficiency and surgical quality of the operating room.

[0071] In other embodiments, the operating room system may also include components such as a main control console, a high-resolution display, a surgical robot, an image fusion system, a telemedicine terminal, an anesthesia machine, and a monitor. The main control console is located in the center of the operating room to facilitate doctors' operation of all equipment, and the high-resolution display is located around the main control console to facilitate the display of surgical images and other information.

[0072] The foregoing embodiments of this application focus on describing the differences between various embodiments. As long as the different optimization features between embodiments are not contradictory, they can be combined to form better embodiments. For the sake of brevity, these differences will not be elaborated upon here. The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art, under the guidance of this application, can make many modifications without departing from the spirit and scope of the claims, all of which fall within the protection scope of this application.
